Perflib_Perfdata.dat

Question

HELP!  This miniscule problem has been driving me crazy... Don't know if any of you 'gurus' out there can help with this...  problem has to do with the  'Perflib_Perfdata.dat'  file which has to do with a sytems monitor file.. My question is - the FACT that the file ext. is  'dat' does NOT necessarily mean the file is ASSOCIATED  with the 'DAT' registered file in the Folders Option/File types etc... This file resides in the Windows\Temp folder and I realize a new file  is created each time you boot up and you can delete previous files (though not the one being used)... This is not the problem or question... I realize there are several Performance monitor file extensions under 'File Types' They are PMA, PMC, PML& PMR.  However Again this may not be the proper file association for ' Perflib_Perfdata. dat'  file,,,, Serached Google, ASK, Dogpile , Doug Knox, Microsoft etc... unable to   find an answer..What was the DEFAULT file association and Icon for 'Perflib_Perfdata.dat' Any help would be very much appreciated....

Having difficulty with editing messages (I think because I'm using IE7 beta).
I wanted to add that in mt case the perflib_perfdata_xxx.dat file in my \temp folder is generated by office.exe. It is a hex file in this case.

There isn't really any one app. .dat files contain data required by whatever app generates them. There is no specific file format for dat files, sometimes they are simple text files (in which case you could open them in Notepad), other times hex, sometimes binary.

See DAT extension

I use quickview plus, which can view most files. However usually the content of dat files is not very illuminating...

If you want to know what is generating a particulasr .dat file, you could use unlocker (that is really meant as a way of unlocking files that 'are in use' so you can delete them if necessary (usually to clean out virus etc.)
